I acquired this watch with a slightly different purpose in mind than your typical trail runner. This past March I set off on a 2100 miles motorcycle road trip to the southern tip of Alaska. With my skis strapped to the bike I tracked my progress as I drove and skied my way up the coast to the promise land.
I set the watch with 2 different functions; a custom "motorcycle" tracker to record my distance, direction and speed on the road and secondly the pre loaded, "alpine skiing" function to track my altitude, duration and speed among other things. The data collected is incredibly accurate as long as you remember to start and stop the function pre and post action.
The best feature of this watch is the ability to sync the watch to your Movescount profile online. The program pulls all your data off the watch to an easy to inspect breakdown of what you did that day and lets you effortlessly compare your "moves" to past dates.
The only set back I was not used to is having to charge the watch each night. The satellite GPS takes far more juice to operate than your typical watch which is kinda annoying but the data it generates is well worth the minor task.
Since the watch has the GPS feature it definitely is slightly larger than your typical watch. With that said it is still incredibly light and not noticeably bulky. The silver casing gives it a very mountainy, french style which goes well with it's main market.
Highly recommend for its intended action sport market and can even branch out into other land roamers...
